Interestingly I couldn't find anywhere on Innolight's website that they were using InP as their active material in the modulators powering those 1.6T transceivers so I asked Gemini what active material does Innolight use in their modulators for their transceivers
I was a bit surprised I got this answer back
Unfortunately, I couldn't find specific public information about the active material InnoLight uses in their modulators. Companies often keep this information proprietary to maintain a competitive edge.
However, based on the general trends in the optical communications industry and the characteristics of polymer-based modulators, it's highly likely that InnoLight uses a polymer material as the active element in their modulators. Polymers have several advantages over traditional inorganic materials, including:
Lower loss: Polymers can have lower optical loss compared to inorganic materials, leading to improved transmission efficiency.
Faster modulation: Polymers can support higher modulation speeds due to their lower refractive index and faster response times.
Lower cost: Polymer-based materials can be more cost-effective to manufacture compared to inorganic materials.
